AUXILIARY BOTTOM FOR WASHBOILERS- Specification of Letters Patent.

Patented June 25, 1907.

Application filed December 18, 1906. Serial No. 348,439-

To (LZZ whont it may concern:

Be it known that I, NELLIE KENJORA, a citizen of the United States, residing at Philipsburg, in the county of Centre and State of Pennsylvania, have invented a new and useful Auxiliary Bottom for Washboilers, of which the following is a specification.

This invention relates to removable auxiliary bottoms adapted for use in connection with ordinary wash boilers, or similar devices, for the purpose of steaming, as, for instance, in the canning of fruits and vegetables.

The invention has for one of its objects to provide a device of this character which is of simple and substantial construction and composed of two adjustable sections arranged to telescope so as to adjust the device to various sizes of boilers.

A further object of the invention is to provide a simple and convenient means for adj usting the sections and permitting the same to be locked in position.

With these objects in view, and others, as will appear as the nature of the invention is better understood, the invention comprises the various novel features of construction and arrangement of parts, which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one of the embodiments of the invention, Figure 1 is a vertical longitudinal section of a wash boiler and the auxiliary bottom in position. Fig. 2 is a bottom perspective view of the auxiliary bottom. Fig. 3 is a fra mentary perspective view of one of the loc ring devices.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

Referring to the drawing, .A designates a wash boiler of ordinary construction in which is arranged the auxiliary bottom B that rests loosely on the bottom 1 of the boiler. The auxiliary bottom B comprises a pair of substantially similar sections 2 and 3 which are adapted to overlap at their inner ends and are adjustable longitudinally for properly fitting in the wash boiler. Each section comprises a top plate 4 which is rounded at its outer end to conform approximately to the curvature of the wash boiler and is provided with a plurality of steam discharging apertures 5 for permitting the steam to pass upwardly from the water space below the plate 4 to the steaming space thereabove. The plates are each provided with a U- shaped rim 6 which serves to support the plates 4 a suitable distance above the bottom 1. The section 3 is slightly smaller than the section 2 so that the rim 6 of the first section will fit Within the rim of the second section, as clearly shown in Fig. 2. The plate 4 of the section 3 passes under the plate of the section 2, and the plate of the section 3 is provided adjacent its inner end with supporting legs 7 connected at their lower ends by a cross piece 8 that bears on the bottom 1 of the boiler and thereby prevents the inner ends of the sections 2 and 3 from sagging at their middle portions. j

The means for lockingthe two sections together comprise a pair of tongues 9 arranged inwardly from opposite sides of the section 2 and secured at their outer ends to the under side of the plate 4 of the section 2. From the fixed ends 10 the tongues extend in wardly parallel with the plate 4 and engage the guides 11 arranged on the under side of the plate 4 of the section 3 adjacent the inner end thereof. These guides are preferably strips of metal bent into the form of a C in cross section, and suitably secured to the section 3. Extending longitudinally of each tongue 9 is 9. depending web 12 which passes freely through the opening or slot 13 of the adjacent guide 11. The web is provided with a plurality of spaced openings 14 in any one of which is adapted to engage a hook 15 pivoted on the guide 11. To unlock the sections for the purpose of adjusting them, the hooks 15 are swung inwardly so as to disengage them from the web 12 and then the sec tions can be freely moved inwardly or outwardly to the desired point, after which the hooks 15 are inserted in the adjacent openings 14.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that the auxiliary bottom is of simple, durable and substantial construction and so designed that its parts can be readily adjusted and locked together to suit any ordinary sized washer or other receptacle in which articles are to be steamed. The various parts of the device may be made of any suitable sheet metal and may be secured together in any approved manner, as by riveting or soldering.

What is claimed is 1. An auxiliary bottom for steaming vessels embodying a pair of slidable sections one overlapping the other, a tongue attached to the upper section and overlapping the lower section, said tongue extending longitudinally of the direction of relative movement of the sections, a web extending downwardly from the tongue and having locking apertures, and a guide adapted to cooperate with said tongue for guiding the sections both horizontally and vertically comprising a sheet of metal having an intermediate portion secured to the underside of the lower section and having its ends doubled toward one another to engage the under side of the said tongue, the web thereon operating in the space between the proximate edges of the doubled ends, and means cooperating with the perforations of the web for locking the sections in adjusted relation.

2. An auxiliary bottom for steaming ves sels embodying a pair of cooperatively arranged sections movable relatively and en gaging one beneath the other, and a locking device for securing the sections in fixed relation embodying a tongue on the upper section extending beneath the overlapping portion of the other section for supporting it, a web on said tongue extending in the direction of relative movement of the sections and having a series of locking apertures, a guide on the other section cooperating with said web and tongue, and means cooperating with said locking apertures for retaining the web and guide in fixed relation.

3. An auxiliary bottom for steaming vessels embodying a pair of relatively movable sections one lapping beneath the other, tongues attached to the bottom of the upper section and cooperating with the underside of the other section and serving to retain the sections in cooperative relation, a web carried by each tongue and having locking means thereon, a guide on the other section cooperating with each web, and means carried by the section having the guide thereon and cooperating with the locking means of the webs to retain the sections in fixed relation.

4. An auxiliary bottom for steaming vessels comprising a pair of relatively adjustable sections provided with supporting rims, a pair of longitudinally extending tongues on the under side of one section having webs extending longitudinally thereof, guides arranged on the under side of the other section and cooperating with the tongues and webs to guide the sections in both horizontal and vertical planes, and devices on the guides cooperating with said webs for locking the sectlons in fixed relation.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
